STEERING-GEAR.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed October 26, 191B. Serial No. 259,738.

To all whom it may concern i Be it known that we, GLENN A. ToAz, WALLACE E. WILBER, and HOWARD E. MAY- NARD, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Steering-Gears, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same. reference being had to the accompanying draw ings, which form a part of this specification.

Our invention relates to gearing and an object of our improvements is to provide for securing two engaging gear wheels with their axes at a proper distance apart. We have shown our invention embodied in a steering mechanism for automobiles.

In the drawings:

Figure l is a portion of an automobile steering gear with some of the parts in section and the gear casing in part broken away.

Fig. 2 is a section on the line B-B Fig. 1.

a is a worm and b is a worm wheel. It is necessary that the worm and wheel have their axis at a certain distance apart so that they shall accurately engage at their pitch lines.

0 is a casing for the gearing. This has a circular aperture 0 through its wall for receiving the bearing piece for the arbor b of the gear wheel I). d is the bearing piece for the arbor of the wheel I). This has a cylindrical portion engaging in the circular aperture 0 in the Casing a. The bearing piece 61 extends outward from the apertime c and has the beveled portion d around its outer edge adjacent to the wall of the casing c. The bearing piece (1 has a cylindrical aperture 61 formed through it longitudinally parallel with its axis and somewhat eccentric to said bearing piece as shown most distinctly in Fig. 2. The arbor of the gear wheel I) bears in said aperture.

6 is an annulus having a beveled or conical inner wall 6 adapted to fit against the 'it thereto, and force the surface 0 against the surface (Z The bearing piece (Z is turned until the wheel I) has its axis accurately at the proper distance from the axis of the worm a. The annulus '6 is then placed in position with the surface 6 engaging the surface (1 and the annulus is bound in this position forcing the surface 6 firmly against the surface (Z by means of the nuts and bolts f f f f. thus causing a frictional; engagement which firmly fixes the bearing piece cl in position and the wheel I) in the position to which it has been adjusted.

g is a set screw having a nut thereon, its outer end engaging the face of the wheel Z near its center so as to restrain the latter from movement in a direction of its axis.

What we claim is:

1. In a train of gearing, the combination of a gear wheel, a bearing-piece, said gear wheel having an arbor engaging eccentrically in said bearing-piece, said bearingpiece engaging in an aperturecoaxia-l therewith, and means acting in a direct-ion substantially parallel to the axis of said bearing-piece for frictionally engaging the latter to hold it from rotation.

2. In a train of gearing, the combination of a gear wheel, a bearing-piece, said gear wheel having an arbor engaging eccentrically in said bearing-piece, said bearingpiece engaging in an aperture coaxial therewith, a non-rotatable ring surrounding said bearing-piece and adapted to engage the same, and means for frictionally engaging said ring against said bearing-piece.

3. In a train of gearing,' the combination of a gear wheel, a bearing-piece, said gear wheel having an arbor engaging eccentri- Cally in said bearing-piece, said bearingsurfaces the cross section of which form an plece engaging 1n an aperture coaxial thereangle wlth the axis of said hearing-piece.

with, a non-rotatable ring surrounding said In testimony whereof, we sign this speci- 1G bearing-piece and adapted to engage the fication. same, and means for frictionall engaging GLENN A. TOAZ.

said ring against said bearing-piece, said VALLACE E. \VILBER. ring and 'said bearing-piece engaging at HOVAR-D E. MAYNARD.
